Feasible Solutions for Global Warming

The global average temperature increased by 0.850 C over a-century-period from 1880 to 2012 and is predicted to increase further between 2.60 C and 4.80 C by the end of the 21st century (Intergovernmental Panel on Climate Change, 2014). Global warming, which is defined as the process of temperature increase on the earth’s surface, due largely to increased amount of greenhouse gas emissions released to the atmosphere, is gradually becoming one of the most serious issues that requires urgent attention of the whole world. The causes of this issue are mainly the result of people’s indifference to the environment which they are inextricably linked with. Increase in deforestation rate, emissions from transportation and release of excessive amount of greenhouse gases into the atmosphere by the usage of fossil fuels are considered to be the main examples of this indifference. With regard to the effects, global warming can lead to some inevitable conditions such as the melting of polar ice caps, longer and more devastating wildfires and severe droughts if enough attention is not paid to. Despite being one of the most serious problems of current world, it could be dealt with effectively if such solutions as decreasing the level of deforestation, greening transportation and switching to renewable energy sources are implemented.

One of the feasible ways to deal with global warming is lessening the rate of deforestation. This is due to the fact that deforestation currently constitutes about 18% of global greenhouse gas emissions, which is a major contributor to global warming (Harris and Feriz, 2011). Hence, the level at which trees are cut should be decreased, which could primarily be achieved by planting trees. To corroborate, new trees should be planted and new forests should be created for areas which were cleared out by deforestation, since they store some amount of CO2 in themselves and thereby prevent it from being released to the atmosphere. As a matter of fact, trees, planted for the area of 1 hectare, can store up to 900 tons of CO2, which is equal to the amount that is released by 147 cars daily (Harris and Feriz, 2011) and as Intergovernmental Panel on Climate Change (2000) concluded, up to 2 gigatones of CO2 can be sequestered annually by tree-planting. Moreover, recycling process can also be a way to reduce deforestation level. Since trees are used for raw-materials such as timber, lumber and particularly paper, focusing on recycling them as well as using recycled ones can reduce the huge dependence for trees, which in turn leads to less cuts and less deforestation. To clarify, as University of Colorado found out, each ton of recycled paper can save 17 trees from being cut or “one ton of recycled paper saves 3700 pounds of lumber”. In addition, recycling of approximately 80 million tons of materials in a year can prevent about 50 million metrics of carbon, which is equal to the amount emitted by nearly 40 million cars yearly, from being released to the atmosphere (University of Colorado, 2016). However, decreasing the level of deforestation might create some problems when it comes to people and to persuading them to plant trees and recycle. Nevertheless, it appears plausible for the government to take some actions and establish some laws and regulations for people to plant trees and recycle. Overall, despite some limitations, reducing the level of deforestation will probably have a positive impact on global warming.

Secondly and even more importantly though, implementation of greening transportation can be another way in dealing with global warming. It is an action which focuses on the development of eco-friendly and sustainable means of transportation and thereby decline in the amount of carbon dioxide emissions from transportation. Since “transportation accounts for 15 per cent of the total greenhouse gas emissions globally”, there is an urgent need to implement this action quickly (Palsson and Johannson, 2016, p674). One of the most crucial steps to start the action is raising the awareness of the public about the competitive advantages of sustainable means of transportation such as bicycles and public transport as well as promoting those vehicles among people so that they can use them more often. For instance, as European Cyclists’ Federation (2011) estimated, bicycle (21g CO2 per km) and public transport (101g CO2 per km) releases 10 times and twice as less amount of CO2 as private cars (271g CO2 per km) respectively and they together can save up to 100 million tons of CO2 together if they are used instead of cars. If people are informed and educated about the positive effects of using eco-friendly transportation upon the environment and global warming by those kinds of facts, statistics and the usage of them are promoted by special advertisements or techniques, people may eventually prefer bicycles and public transport over private cars. Furthermore, increasing the production of fuel-efficient and electric cars can also assist in implementing greening transportation. Cars which are powered by biofuels or electricity are far more eco-friendly than ordinary, petrol-powered cars, in that they release considerably less amount of CO2 (Velazquez et al., 2015). In fact, fuel-efficient and electric cars release 20% and 40% less amount of CO2 correspondingly when compared to cars that run on petrol (Union of Concerned Scientists, 2012). However, it might be true that currently there is no enough opportunity for promotion of sustainable transportation and funding for production of environmentally-friendly cars. Due to this, many people still are not aware why bicycles, public transport and fuel-efficient cars should be preferred by them. Nonetheless, it might be recommended for government to initiate some actions such as providing bicycles and public transport with specific bike and bus lines to enhance the promotion of them as well as increase the level of funding in producing fuel-efficient and electric cars. In essence, if there is some action by government and greening transportation is implemented, the negative impacts of transportation on global warming will probably decline.

The third and the foremost solution for global warming is increasing the usage of renewable energy sources and decreasing the usage of fossil fuels. This is because of the fact that by far the largest – 26% of all greenhouse gas emissions is the share of fossil fuels (Harris and Feriz, 2011). Therefore, the use of renewable energy sources should be accelerated, primarily by involving them more when generating electricity. Although solar and wind energy releases far less amount of CO2 to the atmosphere while generating electricity compared to coal and natural gas, their share still accounts for only 22% of all generated electricity (International Energy Agency, 2015). Increase in this share can assist to significantly decrease the amount of CO2 emissions in the process of generating electricity. This is because in order to generate 1 kilowatt-hour electricity, coal and natural gas emits up to 3.6 and 2 pounds of carbon dioxide respectively, whereas corresponding figures for solar and wind energy are negligible 0.07 and 0.02 (Intergovernmental Panel on Climate Change, 2011). Moreover, applying solar panels and wind turbines for household usage can also boost the use of alternative energy sources. Most household equipments work with electricity that can be generated by solar panels or wind turbines even at home. By installing them according to their needs, more and more families will be able to satisfy their needs to electricity nearly fully. This, in turn, helps to increase the use of alternative energy sources by making opportunities for families to decrease their dependence on non-renewable energy sources. Once there is a gradual increase in the usage of renewable energy sources, it will probably have some positive outcomes related to global warming. Realizing the advantages of alternative energy sources over fossil fuels, increasing number of people, families and countries start relying on them in the process of electricity generation. In fact, the share of renewable energy sources in generating electricity is expected to increase approximately to 30% by 2020 (International Energy Agency, 2015). Most importantly, considerably less amount of CO2 will be released, when there is an increase in the utilization of sustainable energy sources. If the distribution of alternative energy sources in energy supply goes up to around 45% by 2050, the amount of CO2 emissions will be 60% less than that of today (Sims, 2003). On the whole, switching to alternative energy sources by decreasing the usage of fossil fuels will probably impact on global warming positively and have inevitably positive consequences.

Having considered all the things, admittedly, it will not be easy to combat global warming since it is considered to be one of the most serious issues of the 21st century. There will also be some difficulties when implementing the solutions as they have their limitations. Nevertheless, if solutions: reducing the level of deforestation, implementing greening transportation and accelerating the usage of renewable energy sources, are all put in action together with the help from government; individuals understand that it is happening, become aware of its causes and change their attitudes towards the environment, it will be plausible to think about overcoming the problem of global warming and avoiding its devastating consequences. Finally, so as not to be late, it is vital that possible solutions be put into action as soon as possible.

(2015). Instead, they should have listed all authors of the paper.
2. There is lack of consistency in referencing conventions in this essay. For example, in some sources, only the first word in the title is capitalised, e.g., Sims, Rogner, and Gregory (2003). However, in some sources, all words in the article title, except conjunctions, grammatical articles and preposition, are capitalised, e.g., Harris, and Feriz (2011). 3. In some sources cited in the essay, the volume number of the journal is not italicised while it should be, e.g., Pallson, and Johannson (2016).
4. A hanging indentation needs to be used in each reference entry, i.e., every line after the first line should be moved a few spaces to the right.
